Rebtel is offering a new kind of technology. Here's how it works. You provide them with the number of the person you wish to call anywhere in the country, and they give you a local number for them. Then, you save this number on your mobile so you can call your friend whenever you want, for a fraction of your normal international rate.

Visit their website and join them today. You will receive 10 free minutes for registering and 60 free minutes for entering the code provided. That's 70 free minutes.
